to expand on spekesoftly's CAP413 reference, the AIP GEN section UK definitions gen 1-7-58 table 7.2 confirms "climb straight ahead" means track extended runway centreline (i.e apply drift...naughty Chevvron
) but also adds that in Missed Approach Procedures, it means maintain Final Approach Track...so out or in, it's drift every time!!
